Geminal Difunctionalization of Ketones via C─S Bond Insertion of Photogenerated Donor–Donor Diazo Compounds

Angewandte Chemie International Edition, EarlyView.
Geminal difunctionalization of readily available building blocks provides rapid access to molecular complexity. This work introduces a strategy for installing two distinct functional groups on a carbonyl carbon by transforming it into a donor–donor diazo compound, enabling both batch and flow applications with broad solvent compatibility.
